Mass is a measure of an object's inertia. Objects with greater mass have a greater inertia; objects with less mass have less inertia.

A 4.0-kg object is moving across a friction-free surface with a constant velocity of 2 m/s. Which one of the following horizontal forces is necessary to maintain this state of motion?

• 0 N
  
• 5 N
  
• 10 N
  
• None of the above.
  

If the forces acting upon an object are balanced, then the object

• Must not be moving.
  
• Must be moving with a constant velocity.
  
• Must not be accelerating.
• None of these.
  

After a cannonball is fired into frictionless space, the amount of force needed to keep it going equals

• twice the force with which it was fired
• the same amount of force with which it was fired
• 1/2 the force with which it was fired
• zero, since no force is required to keep it moving.
